HYDROCARBON INCANDESC'ENT LIGHT.

SPECIFICATION forming part of Letters Patent Nor/352,821, dated November 16, 1886.

Application filed January 2, 1886. Serial No. 187,464. (No model.)

To aZZ whom it may concern:

Be it known that I, ALEXANDER HEILBRUN, of Cincinnati, Ohio, have invented a new and useful Improvement in Hydrocarbon Incandescent Lights, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings,

forming part thereof, in which- Figure I is an elevation of .my improved burner. Fig. II is an end view of the same.

Similar letters of reference in the several drawings denote the same parts.

Reference being had to the accompanying a is a tube, shown in the drawings as soldered to the pipe a, but it may be screwed to the pipe a in the ordinary manner. Into this tube a the small burning-tubes A are inserted and are projected downward any desired depth. These pipes A flare, and are curved, as shown, and the mouth ends h are brought directly opposite each other. I turn the ends h of the tubes A up, so that the angle of incidence of the flame impinging upon the surface of the substance to be raised to incandescence. shall be such that the deflected flame shall impinge upon said tubes somewhat above their mouth ends and raise the gas therein to a high temperature before itissues.

e, e, and f are members of a holder. rigidly attached to thetube a.

Operation: The tube a is attached to an gas-pipe leading from a gasometer filled with fuel-gas. If, now, it is intended to be used for illuminating purposes, any metal or metallic oxide or carbonate may be inserted into the-holder f to be raised to incandescence. I have shown a flat elongated piece, B, of chalk or carbonate of lime, inserted in the'holder.

The gas issuing out of the tubes A under press 0 ure serves to heat the chalk, and the heat arising from the flame of the burners and the substance heated serves to heat the gas in the tubes a and A before it issues therefrom. If, however, it is to be used for heating purposes only, 4 5 the distance between the mouths h h of the tubes A would vary according to the necessities of the ease. Looking at Fig. I it will, be seen that the fixed ends of the tubes A are much nearer together than the mouths of said tubes. They are so placed that the heat arising from the heated substances may more certainly heat the tubes A throughout their whole length.

Having thus described my invention, what 5 5 I claim as new, and desire to secure by Letters Patent, is as follows:

The combination, with the supply-pipe a and the horizontal blast-tube h, of the hangers 6, depending from'said blast-tube, the support f, secured to the lower ends of said hangers in the same vertical plane as the tube a, the piece B, of incandescent material, having parallel sides supported by said-holder,with its sides vertical and in the same vertical plane as the tube a, and the small tubes'A, having I upwardly-inclined mouth ends terminating in two parallel rows upon opposite sides of the. piece B, substantially as set forth.

' The foregoing'specification of my invention signed by me this 29th day of December, A. D. 1885. j ALEXANDER HEILBRUN.
